Hot-Swapping Switches
The GATERON iG 98 keyboard supports hot-swappable mechanical switches (5-pin and 3-pin compatible). This allows you to change switches without soldering.
- Removing a Switch: Use the provided switch puller. Align the prongs of the puller with the two clips on the top and bottom of the switch. Squeeze the puller firmly and gently pull the switch straight up.
- Installing a Switch: Ensure the new switch's pins are straight. Align the pins with the holes on the PCB. Gently press the switch down until it clicks into place. Do not force the switch, as bent pins can damage the socket.
